To all whom it may concern v 7 Be it known that we, CLARENCE E. BAU- MER and JOHN connnvycitizens of the United the accompanying drawing. f Y

This invention relates to a track 1nstru ment, andthe principal Qb ect of the same 1s States, residing at Troy, in thecounty of v Miam and State of Ohlo,have invented oer taln new and useful Improvements in-Track Instruments, "of which the following is'la speclfication, reference belng had therein to the provision of a devicewhichz may be easily swung to an operative position so as to engage thevalveoperating mechanism of an'engine. f I

Another object "of this invention is, the production of a trackinstrument.having'an eflicient locking means which is adapted to hold the track instrument in an operative position for engagement by the valve controlled mechanism of the engine.

lVith these and other objects in V ew, this invention consists of certain novel combinations, constructions and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying .drawingsFigure 1 isa perspective. view of the track instrument- Fig. 2 is'a' sectionalview through a portion of the track showing the track instrument carried thereby. Fig. 3 is a deare provided withthe enlarged hollowbody 7 for carrying the operating shaft8. This operating shaft extends transversely across tailed perspective view of one of the plates showing the same mounted upon the operating shaft. Fig. 4: is a fragmentary View of anoperating lever which is formedupon the shaft. Fig, 5 is a section taken on the line 55 of Fig. 8. Fig. 6 is a detailed perspectiveview of the locking mechanism which is adapted to hold the track operative position.

instrument in an Referring to the accompanying drawings by numerals l and .2 indicates the usual rails which are supportedoupon the ties 3 and are held in'position by the. usual' spikes 4. 1 1- terposed betweena plurality of the ties 3;

upon the underside of'the flange of the rails 1 and 2 are providedthe supportingjournals 5. These journals5 may be held in fixed engagement with the rails by ahysuit ablemeans such as bolts indicated at; (5 and the track and carries the. sleeve 9 of'a plate 10, this sleeve being held me set position by means of'the set-screw 11'. By the adjustme11tfof this set-screw 1113118 sleeve 9 may be movedalongthe operating shaft 8 so as to allow the plate 10 't'obe positioned in any desired position along "the shaft 8 for en sov gfigement by the valve operating mechanism 7 I of the engine.

. For the purpose of swinging theplates 1O "tofa' verticalposition, the 'operating'shaft 8 i is provided at one end with a vertically extendingoperating lever-'12. This lever 12 {is providedwith'an aperture 13 adjacent its H upper" end through which the cable 14 passes. cable is provided with knots ;1-5-'up0neach side of'the lever 12 as disclosed' n Fig. 4. In this manner it will be seen thatwhen the cable is moved it will c ennpar't a sw nging movement to the lever '12.

This cable lt'is adapted tobe operated by a" stationmaster or other. individual, or by any suitable controlling mechanism not deemed necessary to be herein disclosed.

The end of the cable-adjacent the track in-' strument passes around the pulley 16 car-I r'ied by I the pin. 17 mounted upon the. track -When the instrument is not infuse it. will normally assume the position indicated in so 18 whichis supported by one of the ties 3L 1 full lines in Fig. 2. However, when it is desired to swing the plates to a vertical posi tion forfengagement by the valve operating jmechanism of an engine, the cable will be pulledand will pass around thepulley16 so as to swing the lever 120f a vertical position which will in turn impart rotary motion to 'theshaft 8 whiehwill swing to a position indicated jin dottedlines in Fig. 2 at which time the same is in positioncforuse;

Inasmuch as the valve operating mech= fianism of the engine will strike/one of the plates withconsiderable force it, is well to provide some means for locking the same 1 in a vertical pOSll31OI1,'LIld thus prevent the" plates from being swung or moved1ndegpendently of the cable.

:site end from the lever12 with avertical finger 1'9avhicl1 passes into. the casing 20 I I carried bythe ties .Apivotpin 21 is car- I .ried byflthe'casing 20 and supports the locking shoe 22, this locking shoe 22 being. provided withbifurcated endp23 andiwith the V 2 Accordingly, the operating shaft, 8 isprovided at the .opposolid end 2 1." \Vhen theplates'IO'are. swung toa vertical position this shoe 22 is swung so as to. allow the vertical finger 19 to be positionedf'between the bifurcatedends 23 whereby the operatingshaft '8 will be held against accidental rotary movement. For the purpose of operating this locking shoe 22 there is provided an auxiliary cable 25 is also carried within the casing 20 adjacent the upper portion of the casing and above the shoe 22. This pivot shaft 27 is adapted to carry the bell-cranklever 28 so as to allow the bell-crank lever to freely pivot or swing upon the same. One arm of this lever 28 is secured'to the cable 25' as shown at 29.

while the opposite end of the lever 28 is attached to the solid end 2 1 of the shoe 22 by means of the connecting link 30. The lower portion of the casing 20 is provided with a secondary pivot shaft 81 for supporting the bell-crank lever 32 which is also connected to the cable 25 asis shown at 83 and which is also connected to the solid end 24; of the shoe 22 by means of the connection 34:. After the plates have been swung to the operative position, the finger 19 will extend vertically, at which time the locking shoe 22 is swung into position to engage the same To accomplish this the T cable 25 is moved in the direction indicated by the arrow in. Fig. 6. at which time it willbe seen that. the bell-crank lever 28.will be swung to draw upwardly to the solid end 24: by means of the link 30, whereby the locking shoe 22 will be swung upon the member 21 whereby the vertical finger 19 will pass between the bifurcated ends. The device will then be held in 'a set position so that when the valve operating mechanism of the engine strikes the same any tendency of the shaft 8 to rotate by means of the forceimparted to the plates 10 is eliminated by the locking shoe 22. However, after the engine is positioned the cable is moved in the opposite direction to. the direction indicated by the arrow in Fig. 6 whereby the bellcrank lever 32 will be swung and will draw downwardly upon the solidend 2 l'by means of the connection 34 whereby the shoe will be swungfrom engagement with the vertical finger 19 so as to allow the shaft 8 .to be 1'0? tated for swingingthe plateslO from a vertical position.

From the foregoing description itl will be seen that a simple operating mechanlsm has been produced which is adapted tooperate Y the valve mechanism of an engine and which 1s provided with an efiiclent locking means for holding the device in a set position, this;

locking means being so formed astobe efficiently operatediasdesired.
